For further information see Installation and Maintenance Instructions (IM-P403-53). Application The and controllers are used to monitor the conductivity of liquids. The is wall mounted, and the panel mounted. As they are identical in nearly all other respects, the following information will, for clarity, refer to the. The main application of the unit is for boiler blowdown control, where it monitors the level of total dissolved solids (TDS), causing a blowdown valve to open if the TDS rises above a set point, and an alarm to be signalled at a higher TDS level. The TDS probe may be mounted in the boiler or in the blowdown line. The controller may also be used for monitoring condensate return, signalling a dump valve to open if the conductivity of the condensate exceeds a pre-set level. The is a dual voltage controller for use with a blowdown valve or dump valve to monitor and control TDS levels, usually as part of a steam boiler installation. The front panel has a four digit LED display and two push buttons to select, view, and change functions. An optional front cover lock is available for the, 2.4.7 and a lockable cover assembly is available for the. In normal operation the display shows the actual TDS value. Voltage, ranges, and other operating parameters are set on installation using internal switches. The controller has a programmable probe cleaning (conditioning) circuit (UK Patent No. 2276943), which allows the system to maintain its accuracy even when some boiler scaling is taking place. It should not, however, be regarded as a substitute for a proper water treatment regime. The cleaning (conditioning) time can be adjusted. The controller has adjustable set point, alarm, and calibration. The set point hysteresis is adjustable, providing a damping effect where changes of water circulation at the probe may otherwise cause overfrequent switching of the blowdown or dump valve. An additional filter can be selected to increase the damping effect where the TDS probe is fitted directly in the boiler. A conductivity probe with a built-in Pt100 temperature may be connected to the controller to provide temperature compensation (2%/ C) where the boiler is working at varying pressures. For other applications such as condensate monitoring or coil boilers where the temperature may vary, a separate temperature may be used.
TDS blowdown controls For smaller boilers where the capacity of the blowdown valve is relatively high compared to the boiler size, the blowdown may be set to pulsed, rather than continuous output, opening for 10 seconds, and closing for 20 seconds. This slows the rate at which the boiler water is removed so that the level is not unduly affected, avoiding the risk of triggering a low water alarm. A 0-20 ma or 4-20 ma output is provided as standard, and may be used for remote display of TDS level or as an output to a computerised management system. A security feature allows parameters to be viewed but not adjusted. Probe in boiler shell For systems where the TDS probe is fitted in the boiler shell, the will open the blowdown valve if the conductivity of the boiler exceeds a certain level (set point). As the contaminated water in the boiler is replaced by clean water from the feedtank, the TDS will fall to the set point (less the hysteresis value), when the controller will close the blowdown valve. Probe in blowdown line For systems where the is mounted in the blowdown line, the controller periodically opens the blowdown valve to allow a sample of water from the boiler to pass the (purge). If the TDS is below the set point, the valve will close after the purge time has elapsed. The purge time is adjustable for different blowdown installations, to ensure that all water from the previous sample has been removed from the system, and that the sample is at a similar temperature to the water in the boiler. The may be set to purge either half an hour from the last purge, or for every half hour of boiler firing, (useful for stand-by boilers). If the TDS level is above the set point, the blowdown valve will remain open to allow the high TDS water to be replaced by clean water from the feedtank. The valve will close when the TDS level falls to the set point (less the hysteresis value). When the valve is closed, the controller stores the TDS level in memory so that the last true value is always shown on the display and is output as the ma signal. protection rating IP65 IP65 (Front panel only as protection rating the case is normally inside a boiler panel) Maximum ambient temperature 55 C Maximum cable length (Probe to controller) 100 m Maximum resistance of 0/4-20 ma 500 W (Negative is earthed to boiler at the probe) Minimum conductivity setting 10 µs/ cm or 10 ppm Technical data Mains supply voltage 230 V setting 198 V - 264 V 115 V setting 99 V - 121 V Frequency 50-60 Hz 20 mm cartridge Fuse type 100 ma anti-surge Maximum power consumption 6 VA Alarm hysteresis 3% Probe cleaning (conditioning) frequency* Every 12 hours Probe cleaning (conditioning) duration* 0-99 seconds 0-99 seconds or * Purge time 0-0.99 hour Every 30 min. or Cumulative purge time every 30 min. of boiler firing Continuous or intermittent - Blowdown (off for 20 s / on for 10 s) Ranges (µs/cm or ppm, switch selectable) 10-99 100-999 1000-9990 * If the purge time is set to anything other than zero, cleaning (conditioning) time is automatically limited to 9 seconds to avoid bubbles forming on the probe.
